3 Claims. (Cl. 22li97) This invention relates to bins which may be stacked one upon the other.

The invention provides a bin defined by side and bottom walls, a peripheral angle iron defining the upper extremity of said side wall with the horizontal portion of said angle iron extending outwardly from said side wall, angle iron on said base having a horizontal portion extending to the base of the side walls and a vertical portion extending downwardly from the inward end of said horizontal portion, said side walls tapering inwardly to such an extent that said lower angle iron horizontal portion if on another bin could rest on said upper angle iron horizontal portion.

Figure 1 shows a bin in cross-section,

Figure 2 shows two bins stacked,

Figure 3 shows the bin taper, and

Figures 4 and 5 show details of the bin.

In the drawings, the bin is provided with side walls 12 which may outline a bin of square, rectangular, circular or other cross-section in plan view. The upper edges of the side walls are reinforced by a peripheral angle iron 14 which thereby defines the upper extremities of said side wall. This angle iron 14 is rigidly attached to the upper edge whereby the horizontal arm 16 thereof, extends outwardly from the side walls, and the vertical arm 17 angle iron is attached rigidly to said side walls, preferably to the inner surface 18 thereof.

Rigidly attached to the lower extremity 2d] of the side walls is an angle iron 22 an arm 26 of which projects inwardly from adjacent the lower extremity of the side wall 12 to the apex of the angle iron 22, the other arm 28 of which extends downwardly therefrom. The attachment is preferably effected by inwardly turning the lower edge of the side wall 12 to form an inwardly extending flange 30 to which the surface of the arm 26 may be rigidly attached. To the downwardly extending arm 23 of the angle iron 22 is rigidly attached a bottom member 32 which effectively closes the bottom of the bin 14). The preferred method of attachment is by providing a bottom member of the required area having in addition an edge area 34 which may be turned upwardly and for rigid attachment to the parallel downwardly extending arm 28 of the angle iron 22.

Since it is desired that the bins may be stacked one on top of the other it is necessary that the outer surface of the downwardly extending portion 23 of lower angle iron 22, be receivable within the inner surface of the downwardly extending portion of the upper angle iron. Thus the dimension between such outer surfaces of opposite sides must be less than the dimension between corresponding inner surfaces of opposite sides. By outermost surface of the downwardly extending portion 23 of lower angle iron 22 I include the surface 34 in the preferred construction where the bin bottom 32 is bent upwardly along the outside of downwardly extending portion 28.

It is also necessary that some portion of the horizontal portion 26 of the lower angle iron seat on some portion of the horizontal portion 16 of upper angle iron 14- and therefore the minimum dimension between the horizontal portions 16 on opposite sides of said bin must be less than the maximum dimension between the corresponding horizontal portions 26 on said bin. By such maximum dimension I mean to include the thickness added by the attachment of side walls 20 to horizontal members 26 by the bending of flanges 30 therebelow.

It will be seen from Figure 3 that to provide the required lifting with bins of diiferent height, that the taper on a shorter bin must be considerably greater than the taper on a tower bin. However, it will be noted in both bins that the spacing of the lower angle iron is the same, and the spacing of the upper angle iron is the same so that a short bin may be stacked on top of a long bin and vice versa.

1 claim:

1. A bin defined by side and bottom walls, an upper peripheral angle iron defining the upper extremity of said side wall, with the horizontal portion of said angle iron extending outwardly from said side wall and the vertical portion thereof extending downwardly from the inward end of said horizontal portion, a lower angle iron on said base having a horizontal portion extending to the base of the side walls and a vertical portion extending downwardly from the inward end of said horizontal portion, the diameter of the inner face of the vertical portion of the upper angle iron being greater than the diameter of the outer face of the vertical portion of the lower angle iron.

2. A bin defined by side and bottom walls, an upper peripheral angle iron defining the upper extremity of said side wall, with the horizontal portion of said angle iron extending outwardly from said side wall and the vertical portion thereof extending downwardly from the inward end of said horizontal portion, a lower angle iron on said base having a horizontal portion extending to the base of the side walls and a vertical portion extending downwardly from the inward end of said horizontal portion, the diameter of the inner face of the vertical portion of the upper angle iron being greater than the diameter of the outer face of the vertical portion of the lower angle iron wherein said bottom wall is provided at its edge with an upturned portion and the downwardly extending arm of said lower angle iron is rigidly attached to said portion.

3. A bin defined by side and bottom walls, an upper peripheral angle iron defining the upper extremity of said side wall, with the horizontal portion of said angle iron extending outwardly from said side wall and the vertical portion thereof extending downwardly from the inward end of said horizontal portion, a lower angle iron on said base having a horizontal portion extending to the base of the side walls and a vertical portion extending downwardly from the inward end of said horizontal portion, the diameter of the inner face of the vertical portion of the upper angle iron being greater than the diameter of the outer face of the vertical portion of the lower angle iron wherein said bottom wall is turned upwardly over and rigidly attached to said vertical portion of said lower angle iron whereby said outer surface is defined on said upward turned portion.
